Application voctober i6, 1947,- serial :nog '180,122' a. 4 i 'z oiaimsg-(01.'155--14Y'fV This invention relates to an adjustable seat for lfarmimplements and more particularly'for farm tractors uponA which it issometimes desirable to stand during the operation of the tractor.

The conventional farm tractor is equipped with a seat for the operatorwhich usually is maintained in a fixed' position near the controlequipment of the tractor. Any adjustment of the seats .of such tractorsisusually obtained by theloosening of bolts and the shifting of the seatandgthen againtightening the bolts to hold the seat in the adjustedposition. It frequently occurs that the operator of a tractor maywish'to stand during A,the operation thereof and when such an` occasionarises, thes'eat of the tractorls'eriously interferes with the operatorremaining inal vlsjtaiidi'ng position and yet--staying--withineasyfreach of the tractor controls. s :I r yThe primary object ofthisinvention is to facilitate the vmovement of the tractor seat -toaposi- I A`tion in whichitwill notinterfere withjche, operation of thetractor from the standing position.

Another object is to enable the seat to be shifted relative to thecontrols to a position convenient for the operation of the controlswithout employing tools of any kind.

The above and other objects may be attained by employing this inventionwhich embodies among its features a frame mounted to slidelongitudinally on the perforated seat supporting plate of a conventionalseat support, a seat Welded to the frame and a latch carried by theframe and adapted to coorerate with the perforations in the plate inholding the seat in various adiusted positions thereon.

Invthe drawings:

Figure 1 is a side View partially in section of a seat supporting frameembodying the features of this invention,

Figure 2 is a transverse sectional View taken along the line 2--2v ofFigure 1,

Figure 3 is a perspective View of the adjustable frame, and

Figure 4 is a plan view of the conventional seat plate to which theconventional implement seat is ordinarily bolted.

Referring to the drawings in detail, a somewhat resilient, generallyU-shaped strap seat support I0 has riveted or otherwise attached theretoa conventional seat supporting plate II which is equipped adiacentopposite longitudinal edges with longitudinally spaced perforations i2.As illustrated in Figure 4, these perforations are arranged in spacedparallel rows and under ordinary circumstances, these perforationsreceive attaching bolts by which alconventional implement seat I3 isadjustably supported on the plate II.

In employing this invention, the seat I3 is detached from the plate I Iand welded or otherwise xed to a frame designated generally I4. Thisframe I4 comprisesa pairv of spaced parallelside -barsIS to which areaiiixedadjacent one-end of the frame I4 spacers I 6- w-hichasillustratedfin Figure 3 lie along opposite sidejedges of `the'side bars I5,` andare of a thickness slightly in excess -ofbthe thickness of the plate II.Transversely extending seat supporting-bars I'I y are welded `Qrotherwise fixed to the upper sides of the spacers Sandie thesesupporting bars Il iheseat I3' is welded or otherwise v; permanentlyattachedl.Formed invone ofthe side bars I5 intermediate .its ends, andin a positionv tov align with-onerow lofperforations I 2is an opening I8 for the reception-of the latch finger `to be more fully hereinafterdescribed. Welded or otherwise xed to the ybar I5 having the Opening ltherein along its outer side edge and intermediate its ends, is'a barrelI9 having a longitudinal bore 2n which extends parallel with thelongitudinal axis of the frame I4 and serves as a support for the latchto be more fully hereinafter described.

The latch above referred to is designated generally 2| and comprises alatch arm 22 intermediate the ends of which is welded or otherwisesecured a pintle 23 which extends laterally and is adapted to bereceived in the bore 20 of the barrel I9. The end of the pintle 23remote from the latch arm 22 is pierced to receive a cotter pin 24, andthe end of the latch arm which approaches the longitudinal axis of theframe I4 is upturned to form a latch iinger 25. This latch iinger isoperable through the opening I8 to enter one of the openings I2 in orderto hold the frame I4 against longitudinal shifting movement on the plateI I. YA suitable bracket 26 is welded or otherwise fixed to the seat I3near the barrel I9 and this bracket supports at one end, one end of acompression coil spring 21, the opposite end of which bears against thelever 22, yieldingly to urge the latch pin 25 to enter an opening I2which may align with the opening I8.

In use, the seat I3 as above described is welded to the frame I4 and theframe is then slipped into position over the plate II as illustrated inFigures 1 and 2. With the opening I8 in the frame I4 aligning with anopening I2 in the plate I I it is obvious that the latch iinger 25 willenter the opening I2 and prevent longitudinal shifting movement of theframe and seat relafound. When the desired position of the seatis`reached, the latch linger is entered into the nearest opening I2 and theseat will thus be held' in` the desired position and against furtherlongitudinal movement with relation to theplate` il.

While in the foregoing there has been shown and described the preferredembodimentv of thisV invention it is to be understood that minor changesin the details of construction, combina'- tion and arrangement of partsmay be resorted to without departing frcrn the spirit and scope of theinvention as claimedi Having described the invention what is claimed asnew is:

l. An adjustable seatfor use with a rectangular seatv plate of the typehaving' a plurality of apertures regularly spaced along one sidethereof, said seat including e; frame comprising a pair ci spaced`parallel guide members, one of said -members; being formed with avertical opening registrable with the perforations in the seat plate,said members being adapted to slidably engage the underside of theplate, a pair of spaced parallel spacers superiniposedv on' the upperfaces ofthe guide members adjacent their outermost edges", a pair ofspaced transversely ext-,ending parallel seat supporting plates securedto the upper" faces of the spacers, a seat secured on the last-mentionedplates, a latch pivoted to one 'or the members and having alock'irig endengageable in the opening in the member and'selectivevIy regis-trahie inthe perforations in the seat plate for holding the frame and seat invarious positionsA thereon, said latch projecting beyond the member andresilient means anchored between the underside of the seat and the latchfor yieldingly urging said locking end into locking engagement in theseat plate.

2. A seat assembly comprising a seat supporting strap, a rectangularseat plate secured on said strap andv having a plurality of aperturesregularly spaced along one side of the plate, a frame comprising a pairof spaced parallel guide members,

one of said members being formed with a vertical opening tegistrablewith the perforations in the seat'plate, said members being adapted toslidably engage. the under side of the plate, a pair of spaced parallelspacers superimposed on the upper faces ofthe guide members adjacenttheir outermost edges, a pair of spaced transversely extending parallelseat-supporting plates secured to the upper faces of the spacers, a seatsecured on the lastrnentioned plates, anda latch pivoted to one of themembers and having a locking end engageable in the opening in the memberand selectively registrable in the perforations in the seat plate forholding the frame and seat in various positions thereon, said latchprojecting beyond the member, and resilient means anchored between theunder side of the seat and the latch for yieldingly urging said lockingend into locking placement in the seat plate.
